This invention relates to the art oftoy percussion cap pistols and has for one of its primary objects the provision of a mech anism for the intermittent feeding of a cap bearing tape past a firing hammer whereby the caps may be detonated one after another in simulation of a repeating or machine gun fire. g

A further important object of the invention is to provide a firing hammer to be operated in sequence with the tape feeding mechanism whereby the hammer is being moved to the recoiled position while the tape is being shifted to bring the next cap on the tape over an anvil against which the hammer is automatically directed upon the C0111- pletion of that shift.

Other important objects of the invention are to provide a very simple compact structure of but few and simple parts in order that the toy gunmay be manufactured and sold at a very low price; to provide a toy gun that is safe in the hands of children; and to provide hand operated means for actuating said feeding mechanism whereby the caps may be detonated one after another at thev speed desired by the operator. 7

These and other objects and advantages will become apparent in the following description of the-invention as illustrated by the accompanying drawing, in which s Fig. 1 is a left hand side elevation of a structure embodying my invention;

Fig. 2 a fragmentary top plan view-of the structure;

I form a shell-like housing in two'sec tions-a left hand section 10- and 'a right hand section 11to have a close resemblance to a pistol or revolver of the automatic type. These sections 10 and 11 are substantially symmetrical and have their dividing plane longitudinallythrough the central vertical plane of the gun. The left hand section 10 is employed essentially as acover, while the operating mechanism mounted on the right section in assembly; the cover being employed to cooperate with the other section in.

retaining the moving partsin operative positions; The secti0ns'10 and 11 when brought together form a short barrel 17 protruding from the end of, a'box-like body 18, and a hand grip '19 extends downwardly from the body v1 8.

' cam 12 is formed to have a plurality of projections about its periphery here shown as three in number and being triangular shaped. This cam 12 is provided with a central hub portion 13'with a hole horizontally carried thereth rough tapering from one side to the other to produce a conical bore. The section 11 within the body 18 toward. its center, is provided withv a cupped-boss 14 into the cup of. which is inserted rotatively the end of the hub-13 which has the smaller end of the bore therein. This end of the hub is slotted. A compression spring 15 is fitted by one end into the hub bore from its larger end and is adapted to "be compressively engaged by its 'other'end bythe section 1( That part of the-hub 13 sur-. rounding -,the spring 15 is rotatively re ceived in a cupped boss16 projecting. inwardlyfrom the section 10. The cam. 12 is thus rotatively mounted between the two bosses 14 and 16 and is spring pressed later;

ally against the section 11.

Forwardly and somewhat above the horizontal center line of the cam ,12 is a fixed pin20 extendingihorizontally from the sec tion 11'withinthebodyf18 and on this pin is rotatively mounted the hammer 21.

Above the central portion of this. hammer 21, both of thesections 10 and 11 are cut away to leave a centralreetangular opening through the top side of th'e body 18 and from the forward edge of this opening in. clined ledges 22 and 23 are formed on the respective sectionsto slope downwardly land rearwardly to under and at a distance below the rear edge of that opening, The upper edge of the hammer is formed to enter between these ledges when in" its uppermost e to extend to within the position to fill in the gap therebetween and form a continuous horlzontal fioor thereacross. The upper wall of the body 18 on the section 11 immediately at the rear of the opening is dropped down to form a horizontally disposed surface for an anvil thereunder against which the head 2 1 of the hammer 21 may be brought. This anvil 25 extends horizontally to under the top Wall of the section 10.

Below the pin 20 is another pin 26 horizontally extending from the side of the section 11. A torsion spring 27 is formed to have a central eye of one or more turns of wire placed over this pin 26 and to have one end pressing upwardly against the underside of the hammer 21 with the other end bearing against the lower horizontal wall of the body 18 in the section 11 whereby the spring normally rocks the hammer to carry the head 24 against the anvil 25. The rear end of the hammer 21 is provided with a down-turned rounded arm 28 of a length path of the projections on the cam 12.

The two sections 10 and 11 are provided with holes aligning with the bore through the hub 13. A crank 29 is formed with a shaft 30 adapted to be inserted through the hole in the section 11 and passed on through the hub bore to extend out'through the hole in the other section. The shaft 30 carries a projecting key 31 of a size to enter into the slot in the hub 13 whereby rotation of the crank will turn the cam 12. A leaf spring 32 is carried by the section 11 by slipping its rear end over a pin 33 and under the two downwardly extending lugs 34 and 35 to have the forward free end of the spring disposed over the cam 12. A stop 36 is formed immediately back of the anvil 25 to limit the upward movement of the end of the spring although the spring back of the stop may be pushed upwardly by the projections on the cam 12 as they may be carried around under the spring. A taperoll pin 37 is provided back of the cam 12 in a fixed position extending from the section 11, on which pin a roll of tape 38 may be rotatively placed. The left hand section 10 is provided with a door 39 whicli'may be lifted by pulling out and pushing up on the lip 40, as indicated by the dash lines in Fig. 1, in order that the roll 38 may be placed on the pin 37. The door also has an elongated forwardly extending portion which uncovers the space immediately below the spring 32 extending to the anvil 25. A tape guide is formed by ledges 42 and 43 extending horizontally from each section and carried upwardly and forwardly along each side of the cam 12.

The tape is carried from the roll over these ledges 42 and 43 to under the spring 32 and along thereunder over the cam 12,

. edge of the body top wall. By grasping the handle or grip 19 in one hand of the operator, the crank 29 is then turned by the other hand in the direction to have the projections on the cam 12 come up from the rear to come into contact with the tape and press it up against the spring 32. By thus forcing the tape against the yielding spring, suflicient pressure of the cam projection is created to drag the tape forwardly until that projection revolves down away. from the tape to be relieved of its pressure thereagainst. As the cam is turned around, to relieve the pressure on the tape, another projection slides over the arm 28 on the hammer 21 carrying the hammer down and then moves on to allow the spring 27 to snap the hammer back to its upper position to cause the head 24 to strike a sharp blow against the tape then stationary under the anvil 25 to detonate the cap in the tape by driving it against the anvil 25 above. Continuedrevolving of the crank 29 carries the tape intermittently across under the anvil, moving on the detonated portion and bringing up the undetonated portion while the hammer is released in timed sequence to strike the tape while at rest and lowered while the tape is being shifted. The cam 12 cannot be turned backwards since the projections thereon would come up under the arm 28 when the hammer is in its top-most position and hence cannot move out of the way.

While I have here shown my invention in the form as now best known to me, it is obvious that structural changes, such for example as varying the number of points or projections on the. cam, may be made with out departing from the spirit 'of the invention and I, therefore do not desire to be hammer in the form of an equilateral triangle may strike, a cam adjacent said hammer,
